I heard that the video represented child stars, and how Hollywood manipulates them- I.e.
0:32 being forced to stop acting like a child and having makeup plastered all over them
the lighting change at 1:06 for the exhausting performances she has to do (hence why she's so against it on the 'phone')
1:32 either being bulimia from the pressures to look perfect or going down the path of most child stars and becoming involved with alcohol/drugs etc (hence why her world starts spinning and she's driven mad)
The hands are the industry controlling her life/every move and literally suffocating her (note the lighting change again)
Acting as if everything is fine when in the limelight at 2:53 despite being deeply scared and unhappy in reality
And then eventually being left alone and unwanted after rebelling and/or growing up at the end
